CHARLES BERNI-IARIDT PETERSON, OF PERRYVILLE, MARYLAND.

To all whom it may concern."

, Be it known that 1, CHARLES BERNHARDT PETERSON, a citizen of "the United States, and a resident of Perryville, in the county of Cecil and State of Maryland, have invented certain new and useful Improve ments 'in Fastening Devices, of which the following is a specification.

.The present invention relates in general to a driven fastening device such as nails, spikes and the like, and has for its object to provide a device of this character which is of simple and durable construction, reliable in operation and easy and inexpensive to manufacture and which when in use is interlocked with the material with which it is associated whereby it is positively pre- Other objectsand advantages of the in construction, combination and'arrangement ofrparts which Wlll be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:'

l igure 1 is a side elevational view of the preferred embodiment of the invention positioned as in use, parts being broken away and shown in section for the sake of illustration; I

Figure 2 is an end elevational view thereof; Y Figure 3 is a plan View;

Figure't is a detail view'in section, illustrating the latch mechanism Figure 5 is a detail View ofvthe latch and associated spring; V

Figure 6 is a plan view of a slightly modified form of the invention, especially adapted for use as a railway spike.

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention and more particularly to Figures 1 to 5, inclusive, the numeral 10 designates generally a master nail or spike which includes a shank 11 having a four cornered point 12 and a head 13. The head 13 extends laterally from the shank for a substantial distance and it carries adjacent its outer end a guide nail or spike 1 1. For this purpose the head 13 is provided with a transverse opening 13 the axis of which is parallel to the axis of FASTENING DEVICE.

Specification of Letters Patent. Patented Apr. 18, 1922 Application filed August 31, 1921. Serial No. 497,179.

. the master shank 10 and the upper end of the opening 13 is enlarged to provide a seat 13. The guide nail or spike 14 includes a shank 15 which snugly fits the opening 13 and a head 16 which is snugly received on the seat 13 so that when the shank 15 is received in the opening 13 and the head 16 is received on the seat 13 the guide nail 14 will extend in parallel relation to the master nail. The shank 15 is provided with a guide opening 15 which extendsobliquely through the shank 15 of the guide nail or spike l4 and which is aligned with the opening 17 provided in the shank 11 of the master spike 10.

A looking or cross spike'l8 is provided and has a head 19 wvhich: is received in a cavity 20 provided therefor in the head 13 of the master spike 10, and a shank 21 which extends through the guide opening 16 of the guide spike 1 1 and through the alined opening 17 of the shank of the master spike, the opening 17 thus constituting a seat or bearing for the shank of the locking spike. The cavity 20 includes an obliquely extending opening 20 which slid-ably and snugly receives the'shank 21 of the locking spike and a; seat 20 upon which the 'head 19 ofithe locking spike 18 is received, As shown'in Figure 1, the underside of the head 20 of the locking spike is a plane surface and snugly fits a similar plane surface of the seat 20 formed in the cavity 20 and these plane surfaces are arranged at right angles to the axis of the. shank of the spike and of the openings 16 and 17 thus providing for a complete nesting of these parts in assembly.

Latching mechanism is provided for'positively securing the locking spike in position, that is for interlocking it with the master spike. and for this purpose a cavity 23 is provided in the shank 11 of the master spike and communicates with the opening 17 thereof. A swinging latch 24 is pivotally mounted in the cavity by means of the pivot pin 25 and is urged out into locking position by means of a bowed or bent blade spring 26. The shank 21 of the locking spike is provided with a locking shoulder 27 which engages the swinging latch :24 in the assembly to bring about the interlocking of the master spike and the locking spike.

In practice, with this form of the invention the master spike is first driven into the wood or other material and the guide spike is then driven through its opening'in the head of the master spike. Whenithe guide spike is completely driven into the wood the interaction of the head of the guide spike and the seatprovided therefor'in the head of the master spike results inthe disposition of the guide spike in parallel relation to the master spike with its guide opening 16.

alined with the opening 17 It isobvious thatif desired the guide spike can bemad'e integral or rigid ivith the master spike and in thatevent it would be driven simultaneously therewith. In either. event the locking spike is next driven and it passes through the guide opening 16 and through the opening or hearing 17 until-the latch 24 snaps into engagement with its shoulder127.

"It is to. be noted that the sh'ank2'l of the locking spike is guided by the openingQU? of the cavity 20 toinsure its entering the guide opening 16. \Vhen this occurs the head 19 ofthe locking, spike is completely nested in the cavity 20 provided therefor in the master spike and the head of the spike presents a continuous and uninterrupted surface.

The embodiment of thefinvention shown in Figure 6 is identical in all respects with that shown in Figures 1 to 5 andabove de- SCribed except that the head of the, master bolt is. provided with laterally extending lu s 291which are adapted to engage the openings alined with the obliquely extend-' ing opening of the headof the master spike, aflocking spike includinga shank extending through said alined openings, and a head received in the obliquely disposed seat, said shank of said master spike having a cavity therein communicating with the obliquely extending opening, a swinging latch pivotany mounted in sald cavity, and a springfor urging said latch to operative pos1tion, said shank of said locking bolt having a locking shoulder cooperable with said latch.

2 A fastening device of the character, described comprising a master s ike including a shank and a laterally exten ed head, said head having an opening extending transversely therethrough and having a seat, a guide spike having its shank extending through the opening and havin a head received in said seat, thehead o the master spike also havin an obliquely extending opening and an o liquely dis osed seat, the

shank of the guide spike anc the shank of the master spike having obliquely extendingopenings alinedwith the obliquely extending opening of the head of themaster spike, a locking spike including a shank extending through said alined openings and a head receivec in the obliquely disposed seat and latch mechanism carried by the shank of the master spike and cooperable with thelocking spike.

3. In a fastening device, a master spike lIlCllLCllll a head, a guide spike associated with tlie head'of the master spike and a locking spike carried by the head of the master spike and. extending obliquely. through the guide spike and tlie'master spike, and latch mechanism for interlockingthe master spike and the. lockingspike.

4.. In a fastening device, a master spike including ahead, a guide spike associated with the head of the master spike and. a locking spike carried by the head of the master spike and extending obliquely through the guide spike and the master spike. V 5. In a fastening device, a master spike including a head and a shank having obliquely extending and alined openings, a locking spike extending through the openings of saidhead and shank and latch mechanism carried by the shank and cooperable with the locking Spike. w h
